Hi,

Can you try the following

step-1:       Goto Terminal>Type sudo su postgres

step-2:        Type "psql database_name"

step-3:        update ir_module_module set state='to remove' where name='module_name' and state='installed';

• run ./odoo-bin shell -c xyz.conf -d test_db

• Search module by using bellow script self.env['ir.module.module'].search([('name','=','module_name')])  then you get the result like "ir.module.module(1060,)"
• Uninstall module using button_immediate_uninstall() function 

self.env['ir.module.module'].search([('name','=','module_name')]).button_immediate_uninstall()

Hi,

There is no option in odoo to uninstall module through command line check 

./odoo-bin --help for possible option in command line
